Hi. GPS sends 2 values separated with null character :

“lat lon” - where space is null character.

3

String or float?

4

String with floats

“23.33232 34.44444”

Hi,

I tried this:

The code in the function block is

var ttt = msg.payload;

ttt = ttt.split(null);

msg.ttt = ttt;
return msg;

It seems to return only a single element in the array - the data in debug is the lat

What am I doing wrong?

Thanks
Nico

null is not null character. null character is “\0”

GPS sends 4 values, although last two for a some time could be 0:
Latitude
Longitude
Altitude
Speed

All separated by ‘\0’ character

Hi Nico,

Did you reve resolve this last year? I get the same. Also for gyro sensor too? Debug node only shows the X axis values or the latitude. I can only get the strings first elements.
